Popis: The extraction separation of Ce and Y by benzyldibutylamine (BDBA) in the presence of ethylenediaminetetraacetic acid (EDTA) as complexing agent has been investigated. The separation factors αCe/Y, in absence of complexing agent ranging from 20–40, increase at proper EDTA concentrations by 1–2 orders of magnitude. The separation of Y as minor or even trace element from the major Ce is so efficient that its concentration in the organic phase lies below the detection limit of the analytical method.
